Need Help??

At 5 characters

my @keys = keys %{{f}};
[download]

is much more elegant than the equivalent

use List::Util qw( shuffle uniq pairkeys );
my @keys = shuffle uniq pairkeys f;
[download]

Remember that hashes do uniq'ing and shuffling for free :)

UPDATE: added a missed "keys" as LanX pointed out.
